Reading CDP packets

2

NOTE

The device can interpret only the information fields that are common to both CDP version 1 and CDP
version 2.

NOTE

When you enable interception of CDP packets, the device drops the packets. As a result, Cisco
devices will no longer receive the dropped packets.

Enabling interception of CDP packets globally

To enable the device to intercept and display CDP packets, enter the following command at the
global CONFIG level of the CLI.

Brocade(config)# cdp run

Syntax: [no] cdp run

The feature is disabled by default.

NOTE

If CDP is globally enabled on a Brocade device, all the interfaces, by default, have CDP enabled on
it. In this case, the show run command does not display any running information about the CDP
configuration in its output.

Enabling interception of CDP packets on
an interface

You can disable and enable CDP at the interface level.

You can enter the following commands.

Brocade(config)# int e 2/1

Brocade(config-if-e10000-2/1)# cdp enable

Syntax: [no] cdp enable

By default, the feature is enabled on all the interfaces once CDP is enabled on the device.

NOTE

To remove an interface from the global CDP configuration, run the no cdp enable command in the
interface mode explicitly. In this case, the show run command displays the running configuration
information for the specific interface at that instance.

NOTE

CDP is not supported on VPLS/VLL endpoints. By removing CDP from the configuration, the no cdp
enable will stay in the configuration.

Displaying CDP information

You can display the following CDP information:
